CO2 EMISSIONS BALANCE FROM BIOFUELS: A BIBLIOMETRIC REVIEW

Resumo

In the ongoing quest to mitigate climate change and reduce environmental impact, the substitution of fossil fuels with biofuels has emerged as a critical strategy. Ethanol and biodiesel, as renewable biofuels, offer a promising alternative to traditional gasoline and diesel, respectively, understanding the carbon dioxide (CO2) equivalent emissions of these fuels is key to evaluating their potential benefits. Gasoline and diesel, derived from petroleum, are major contributors to greenhouse gas emissions, particularly CO2. When combusted, these fossil fuels release significant amounts of CO2, a greenhouse gas that contributes to global warming. The carbon intensity of gasoline and diesel is high, making them a primary target for reduction in efforts to combat climate change. In contrast, ethanol, primarily produced from crops like corn or sugarcane, and biodiesel, derived from vegetable oils or animal fats, offer a lower carbon footprint.
